Flash Copy / BCV Backup on DB2 v9

Hello,
We are in the process of implementing BCV Backups or more commonly known as Flash Copy backups on our SAP databases. Anyone out there running this in their shops? Any tips?
Also, does anyone know if I restored from a split mirror image of a database that was in rollforward pending, does rolling forward through the end of logs or a PIT bring the database to a consistent state? Is this supported by IBM and SAP?
Thanks guys!
Florencio

Thanks Raja! It's good to hear that you've had success with this technology. By the way, if you get a chance can you please review the steps outlined below on how we are going to implement our split backup process? This may also be good basic resource material to other shops thinking of implementing the same technology for their SAP systems:
Backup Steps:
1. Synch the disks (Establish).
2. Suspend Database I/O - db2 "set write suspend for database"
3. Split the disks.
4. Resume Database I/O - db2 "set write resume for database"
5. Mount the filesystems onto the Target System.
6. Start DB2.
7. Initialize the database as STANDBY - db2 "db2inidb $ as standby"
8. Run a DB2 Backup.
9. After backup completes, Stop DB2.
10. Unmount filesystems.
11. Send backup images to tape.
Restore Steps:
1. Stop source database.
2. Unmount filesystems.
3. Reverse Establish from the target server to the source server.
4. Split the disks
5. Mount the filesystems.
6. Bring up DB2
7. Initialize the database as MIRROR. db2 "db2inidb $ as mirror"
8. Rollforward to end of logs or PIT.
9. Activate DB
10. DB and Basis Sanity Checks.
If the above steps should fail, then our contingency plan is to restore from the DB2 backup taken using the steps below. The steps would be the normal steps when doing a DB restore.
1. Mount the BCV backup directory to PRD.
2. Issue DB2 restore command.
3. Rollforward to end of logs or PIT.
4. Activate DB
5. DB and Basis Sanity Checks.
Let me know what you think.
Thanks,
Flo

Recovery using Full BCV backup & archive logs

Hello DBA's ,
I have Last Sunday's Full BCV (Buisness Copy Volume) backup (i.e. ..... the tablespaces were taken into Backup mode then Sync the BCV, then split the BCV , take the backup of BCV and take the tabespaces in normal mode in short what we call as HOT BACKUP ........ ) & also I am taking only archive log & control file backup Daily.
Now I want to Run my database on Different Server using the above FULL BCV & daily backed up Archive logs & Control file.
Kindly update me- Can I go for following recovery steps for above scenario.
1) Install ORACLE software on new server.
2) Restore the last Sunday's FULL BCV (Hot backup)
3) Restore the archive log from last Sunday's Full BCV backup.
4) Restore the latest backed up control file.
5) Mount the database.
6) Recover the database using backed up control file & archive logs.
7) Open the database with RESETLOGS option.
Please Guide me whether I can Fully Recover/Start database on this new server using above steps. ---OR---- " Are there any more files except data files that need to be backed up daily after Full BCV ? " ---OR ---- More suggestions are Welcome.
I want to test this scenario bcz.
a) I can't afford daily BCV due to lack of storage with current retention given by buisness.
b) I can't afford long time taken by RMAN for backup & recovery, as it disturbs my other backup shedules, also RTO should be very low as per my buisness requirement.
c) Currently we are not thinking for any another Backup options.
OS platform -- SOLARIS 10
Database version -- ORACLE 9i/10g

Hello everybody ....
Actually I am doing the above scenario practically and I am facing the problem that when I am applying my archive logs using backup controlfile until cancel, the recovery completes upto the available Archive logs/sequence. But it throws the following error along with it ......

ERROR at line 1:
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: '/oracle/EPR/sapdata1/system_1/system.data1'
So, I opened my database using Last (Sunday's) full hot backup only and it opens successfully without applying any archives.
Now, my question is... why my database doesn't open with OPEN RESETLOGS option when I am recovering it using command " RECOVER DATABASE UNTIL CANCEL USING BACKUP CONTROLFILE; "
I want to recover my database upto Saturday then What should I do ?
Please help me out !

Homogenous System Copy WAS 6.20 DB2 8

Hi all.
I am planning to do a Homogenous system copy of our PRD system to the QAS system. Both have SAP R3 4.70 Core with WebAS 620 and DB2 version 8.
I am reading both guides 6.20 and 6.30 and it is not clear if with WebAs 620 and version 8 if I can use the database relocation method or the backup method. It says that u need DB2 8 but not sure if 620 o 630. Could someone clear this doubt.
I know that the R3Load method is possible but if the backup method or the relocation method is possible I would like to use this since this backups the whole DB and the r3load doesn't.

Here is the link to the thread

RMAN and IBM Flash Copy

Has anyone had experience using IBM's Data Protection for Flash Copy with necessary for backups? The IBM documentation mentions a "backup database server" and that "Oracle Server" must be available on both prod and backup servers. Does this mean that there is another instance running on the backup server or is it just necessary to have the Oracle software loaded on the bu server?

Hi David
1.yes u need large undo tablespace that hold information for long time.
and set undo retension parameter according to need of flashback query.
But Don't set "Retention Guarantee" because when u set this parameter it will fail DML transaction on database.
because it will give importance to retail data in undo.
In simple Scenerio(No Guarantee Mode)
if DML required undo space in undo tablespace then it will overwrite expired undo and select query may be fail with "snapshot too old error"
But when u set it to undo retension then
oracle will not able overwrite on expired undo and u r DML query fail..........
so in normal prod database we will give more importance on DML query rather then Select query
so Don't use undo retension to gurantee mode.
But u can use in dataware house where query take long time to fetch result even in days.
2.u need to config MML for taking backup of rman to tape directly.
Thanks and regards

How can I restore backup if I copy the backup (Think Vantage RR 4.0) to another storage

After I copy a backup to another storage, it is not possible to restore this backup, because the old path, from the other storage is entered. Is there a possibility to change this path and restore the backup?
thx for help!

Are you launching the restore operation from within Windows?
You may be able to browse to the copied backup if you boot R&R from a CD/DVD.

Don't you just love changes in interfaces?
I found the answer to my question.
When you attach a device (iPhone, iPad) to your Mac, in iTunes 12 in appears as a tiny icon in the second "row" of the iTunes display. Click the icon and the familiar iTunes display for the device appears. From there, on the Summary screen, you can see the dates of the backups of the device (iCloud and backup to the computer). You can also use the button to backup to the computer.

Can I copy a Backup file from one PC to another and use it?

IPhone got all screwed up with the update on my home PC and wont restore, my PC at work does it fine, but my backup file is on my home PC. Can I copy my Backup file from my home PC and put it on my work PC to restore my IPhone?

Before your restoring your iPhone with your PC at work, you can create a backup of your iPhone on the PC before restoring.
With your iPhone connected and available in the iTunes source list, control click on your iPhone and select Back Up.

How can I copy a backup file from one computer to another?

I am having to install tbird again on a new system, I copied and backup-ed my previous emails. When I view my copies and/or restored email files are empty. Why?

I am having to install tbird again on a new system, I copied and backup-ed my previous emails. When I view my copies and/or restored email files they are empty, nothing is displayed and the window shows message of being empty. I an sure of the backup and of my copy/paste steps. Where and/or what has happened to my emails? I also searched each disk and all files for email extensions (*.mozmsgs and *.sbd and *.sbf) with no results. I can not find a way to restore over 10 years worth of very important emails. Can someone please help me recover what I know is their? All my emails in Seamonkey are on another system (the one I replaced with new win7 pro 64 i7 based system) and all the emails I had in tbird, before having to reinstall everything on new system due to something that happened to the os, are the copied and backup-ed files that are showing empty. Prior to new install all old Seamonkey emails transferred to tbird and all the tbird emails prior were their and were the copied/backup-ed files showing empty now. This is turning into my worst experience and nightmare in over 25 years of systems. I am really lost on this one. please help....

Are you saying you split your profile between C and D drive, perhaps through specifying a location in the account settings.
BTW.
*.mozmsgs useless duplicate files created for windows search integration. Simply wasted space on the disk.
*.sbd a folder indicating the presence of a sub folder (contains no mail at all.
*.sbf (I don't know that one.
*.msf an index of mail. contains tags, but otherwise useless and will be recreated when the mail is loaded in Thunderbird so it can display the mail list.
*. that is no file extension. You mail in files with the same name as the folders they came from.

System Copy/ Oracle Backup/Restore as part of migrating from 32 to 64-bit

Source system (I386): R3E47 Ext Set 2.00 SAP_BASIS 620 Kernel 640 Windows 2000, Oracle 10.2.0.4, non-unicode
Target system (x86-64/AMD64): R3E47 Ext Set 2.00 SAP_BASIS 620 Kernel 640 Windows 2000 Oracle 10.2.0.4, non-unicode
Am using method System Copy/ Oracle Backup/Restore to migrate from 32 to 64 bit (HOM System Copy).
Actions on source system:
a) Upgrade from 9.2.0.7 to Oracle 10.2.0.4
b) Used ora_br_copy.bat to generate CONTROL.SQL and init<sid>.ora
c) Switched logfiles
d) Performed offline backup
Actions on target system:
a) Installed Oracle 10.2.0.1 and patched it to 10.2.0.4
b) Used CD 51033746 "6.20/6.40 based products Installation Master (Edition May 2008)" to install the CI
c) Started installation of the DB instance selecting System Copy/ Oracle Backup/Restore (same <SID> for source and target systems)
Relevant input parameters used:
Database schema: SAPR3
Database character set: US7ASCII
d) When SAPINST stopped to allow for restoring of datafiles, logs and init<sid.ora>:
- copied datafiles and logs to the usual place
- copied CONTROL.SQL (edited to include utilrp.sql and utlrp.sql for the migration from 32 to 64) to the DB-instance intallation . directory.
- copied generated init<SID>.ora to the <ORACLE_HOME>\database
e) Resumed SAPINST.
David Byrne in a previous post suggested: "check your oracle alert file in case there are errors there you may need to update the word size for the 64bit install. Errors like this in the oracle alert file would suggest that.,
ORA-12012
ORA-06544: PL/SQL: internal error, arguments: [ORA-06544: PL/SQL: internal error, arguments: 56319], [, ], [, ], [, ], [
ORA-06553"
Well, I am getting ORA-06553: PLS-801: internal error [56319] but then my edited CONTROL.SQL (which is mainly a CREATE CONTROLFILE as it would be obtained with a ...BACKUP CONTROLFILE TO TRACE) includes at the end this:
shutdown immediate
startup upgrade
spool utlirp.log
@?/rdbms/admin/utlirp.sql
spool off
Shutdown immediate
Startup
Spool utlrp.log
@?/rdbms/admin/utlrp.sql
Spool off
exit
which is supposed to do just that... (I think)
Help, anyone?

> Trying to cheer me up, are you?
No
> It is NOT free that reorganization! Quite expensive, actually, paid for in time! But you're right... the database needed a reorg anyway :-\
True, not "free" - it takes time but the data will be nicely aligned then
> And why would I have to reconfigure all those 10.2 features? Everything's either in the database or init<sid>.ora, ain't it? And my database is a pretty 10.2.0.4 with all those nice features already activated...
No - not really auotmatically if you upgraded from 9.2 And "init<SID>.ora" is past, you nowadays use "spfile" If, of course, e. g. Automatic Undo was activated in 9.2 then it's there of course in 10.2 too.
> One sticky point... I haven't really read the r3load procedure yet and I will before I import, but... I would say I don't have to do anything about the 32->64 bit, right? I mean, it should behave properly while reloading on 64-bit...
The exported content is about 10 % of the size of the system, it's database and OS independent so yes, you can import it nicely on 32bit. Another tip: make sure you don't just use the default configurations for R3load, it will take a HUGE amount of time. Use the package splitter (builtin-in in sapinst) so you get a much higher parallelism when importing.

Can I copy old backups from an external HD to a new one? Thanks for your help.

I'm using time machine on an external hard disc (1 TB) for more than a year now. Now the eHD is nearly full and I would like to change to a bigger one. Is it possible to copy the backups from the old one to the new one? Thanks a lot for your help.

Hello Joe Gramm. Thank you for the link. This is what I was trying to do 2 days ago. I think the problem is, that the old eHD doesn't have the "Ignore ownership on this volume" button, while the new one has it. Therefore I tried to change the rights of access on everything (see above)... Trying to copy now brings me the following message: "Das Backup kann nicht kopiert werden, da beim Backup-Volume kein Eigentümer aktiviert ist." translatet something like: the backup could not be copied, because there is no owner activated on the backup-volume. Do you have any ideas how to change that or how to proceed? Many thanks for any input!

Copy or backup to external hard drive

Could someone help me copy or backup my music to an external hard drive? I tried, but what ended up on the hard drive doesn't look familiar to me at all.
thank you in advance

If the songs in your library are not all in the iTunes Music folder you should start by consolidating them. When you consolidate, any songs in the iTunes Library that are not in the iTunes Music Folder are copied to the Music Folder and the Library is updated to point to those new files. Files already in the iTunes Music Folder have no changes made to them: Copying all your iTunes files to one location - Windows
Once you have everything safely in the iTunes Music folder copy the iTunes folder from your internal hard drive to the external drive. Copying the whole folder brings with it the iTunes Music folder and also the iTunes Library (iTunes Library.itl in Windows) database file which holds all the information about your songs (Playlists, Ratings, Play Counts, Last Played, Date Added, etc). You'll get more information including the Folder/File structure in this article: What are the iTunes library files?

Hi,
Could you please check whether db2<sid> user has write permission on this folder ?
Also, could you please paste db2diag.log when you run the backup and it hangs ? Please also paste output of below command when you start the backup:
db2 list utilities show detail
Please also let us know which backup are scheduling from db2 command line.
Thanks
